Respondents may try to complete your web survey multiple times
("stuff the ballot box") to receive free incentives, to register
dissatisfaction, or for any other reason. Or, web surfers who are
not part of your target audience may happen across your web survey
and complete it. Either of these can skew and invalidate survey
results. But requiring your audience to remember and type in passwords
creates an obstacle to their responding. Form Maker's unique Positive
Respondent Identification™ (PRI) system ensures survey and data
integrity without introducing respondent obstacles.
Positive Respondent Identification™ (PRI) ensures that only authorized
respondents can access your web survey and that they can complete
it only once. PRI inserts a unique ID code into the email invitation
to the web survey for each respondent. Each email invitation contains
a seperate id number, so the respondent does not have to type in,
remember, or even be aware of the code. Before the survey is displayed,
the PRI code is checked against a database to ensure that the code
is valid and has not previously been used. If the code is valid,
the survey is displayed. After the respondent completes the survey,
the database is updated so the code cannot be used again. If a respondent
tries to use a code that is invalid or has already been used, a
message reporting that fact is displayed.
A clock will run on each survey, so that we can know how much time
respondents spent to read survey questions.
